The Zodiac Killer 2023 Guide: Decades of Murder and Research

During the Covid-19 pandemic, Shannon Marin began to delve into online material and books about the Zodiac case and similar killings. He was amazed by the large number of insights that existed and had mostly been discarded. Studying the case felt like looking at a table with a handful of pieces to a jigsaw puzzle and then finding that dozens and dozens of matching pieces were lying on the floor. Corresponding with Sandy Betts, Shannon explored a complex scenario in which the body count was probably well over 100. As the weeks and months went by, Shannon came to accept that the Zodiac killer was active at least into 1999. Shannon hopes that this book will motivate both professional investigators and amateur researchers to consider Zodiac as a valid suspect in many unsolved homicides. In the 1960's, and especially 1969, Sandy Betts suffered bizarre harassment and attacks. Sandy worked in Vallejo, California, but did not at first associate the malicious acts with Zodiac. Unable to give the police useful information, she had to persevere through years of stalking and lethal danger. In 1990, Sandy began to study the Zodiac case seriously. She spent hour after hour researching confirmed and possible Zodiac attacks. Sandy connected with many people investigating and contributing analysis to Zodiac and related crimes. She has also been able to fit many of the pieces of her part of the Zodiac puzzle together. Her view of Zodiac, which she equates with the individuals who attacked and harassed her, is that they were evil and caused terrible suffering for the friends and families of many, many homicide victims. Sandy Betts has provided the moral components of trying to stop attacks and give resolution for the people who have lost loved ones over the years.
